At a Glance
CPAP supplies are the essential parts — like masks, tubing, filters, and humidifier chambers — that help your machine deliver effective sleep apnea treatment. Optional accessories like mask liners, chin straps, and pillows can enhance comfort and make CPAP therapy easier to stick with long term.
The right CPAP supplies can make a big difference in how comfortable and effective your sleep apnea treatment feels. From masks and tubing to filters and humidifiers, each component plays a role in delivering consistent airflow and maintaining a proper seal. Over time, these parts can wear out or collect buildup, which may affect performance and comfort.
In this article, we’ll explain the different types of CPAP supplies, how often to replace them, and tips for choosing the right options for your needs.

Essential CPAP Supplies
CPAP supplies can be divided into two categories. Essential supplies like hoses and filters are required in order to use your CPAP machine. Optional supplies, such as chin straps and CPAP pillows, can make therapy easier or more comfortable.
Below is a list of the items that are necessary for the basic functionality of a CPAP machine. Without them, the device wouldn't be able to provide safe and effective sleep apnea treatment.
CPAP Masks
CPAP masks are the part of the system that delivers pressurized air from the machine to your airway while you sleep. There are three main types of CPAP masks, each designed to suit different breathing habits and comfort preferences:
- Full-face masks cover both the nose and mouth
- Nasal masks cover just the nose
- Nasal pillow masks use small inserts that sit just inside the nostrils
Regardless of the type, each CPAP mask is made up of three main parts:
- CPAP mask frames: CPAP masks have a frame that holds the mask cushion in place. They vary in size and shape in order to better accommodate different face shapes and features.
- CPAP mask cushions: Mask cushions are designed to seal tightly against the user’s face to deliver pressurized air to the nose or mouth and nose.
- CPAP mask headgear: Headgear holds the mask frame in place using straps of flexible material that go around your head and attach to the frame with clips, magnets, or Velcro.
CPAP Hoses
CPAP tubing delivers pressurized air from the machine to your mask. Most machines come with standard 6-foot hoses, but shorter or longer options are also available.
CPAP Filters
Depending on the brand and type of machine, CPAP filters can be either disposable or reusable. Both filter types need to be replaced on a regular basis, but reusable models are washable and last longer.
CPAP Humidifier
Though a CPAP humidifier isn't technically essential, most modern CPAP machines have then built in, though stand-alone units can be purchased separately.
- Humidifiers: Humidifiers add moisture to the air flowing through the CPAP system and are used to help prevent dry mouth and similar side effects.
- Humidifier water chambers: This removable reservoir holds distilled water that's used to add moisture to the air.
Optional CPAP Accessories
For many people with sleep apnea, the health benefits of CPAP therapy outweigh the uncomfortable feeling of wearing a mask to bed. But if you find that discomfort is interfering with your sleep or your willingness to adhere to nightly therapy, consider purchasing an optional CPAP accessory designed for comfort.
- CPAP mask liners: CPAP mask liners can help reduce skin irritation and redness caused by a CPAP mask. They're usually made of a soft fabric that forms a barrier between your skin and the mask cushion. In addition to comfort, mask liners can help lengthen the life of a cushion by limiting contact with the skin.
- Heated CPAP hoses: Heated CPAP hoses have coils around the exterior of the tubing to keep the air inside at a warmer temperature. Heated tubing is designed to prevent condensation from forming in the hose and mask (also known as rainout) and may help relieve CPAP side effects like dry mouth and dry nasal passages.
- Chin straps: CPAP chin straps are designed to keep the mouth closed, thus minimizing the potential for mouth leaks during nasal CPAP therapy.
- CPAP pillows: CPAP pillows are specifically designed to accommodate masks, hoses, and headgear. They often feature cutouts and supports to allow you to sleep on your side while preventing your mask from applying too much pressure on your face.
- CPAP batteries: Generally, CPAP machines don't require batteries, as they have power cords that plug into electrical outlets. You may want to consider purchasing a battery pack for international travel or camping trips or if you live in an area prone to power outages.
- CPAP cleaning supplies: While the most effective CPAP cleaners are mild soap and warm water, CPAP wipes can be useful for keeping your mask free of dirt and oil, though they don't replace regular cleanings. There are no ultraviolet light or ozone cleaners approved by the U.S. Food and Drug Administration (FDA) for cleaning or sanitizing CPAP machines.
What to Consider When Choosing CPAP Supplies
To help narrow down your options when searching for CPAP supplies, keep in mind some basic considerations.
| Medical Recommendations | While you do not need a prescription for many CPAP supplies, you may want to discuss with your doctor which supplies are best for you. There are options that can enhance your experience while providing the same therapeutic effects, but not everyone will benefit from these accessories. |
| Machine Compatibility | Not all supplies work with all machines. In order for your CPAP device to function appropriately for sleep apnea therapy, you must have parts that fit your specific machine. |
| Lifespan | CPAP supplies have a regular replacement schedule, and it isn't advisable to use them past their recommended lifespan. |
| Material Quality | Consider the type of materials used, the reputation of the manufacturer, and customer reviews before purchasing CPAP supplies. |
| Warranty | For each type of supply item, warranties can vary depending on the manufacturer and the seller. It's important to consider both the length of the warranty, as well as the specifics of what's covered. |
How to Buy CPAP Supplies
Buying CPAP supplies is generally straightforward, but it’s helpful to understand a few key factors before you shop. Requirements around prescriptions, insurance coverage, and where you purchase your supplies can all affect cost, convenience, and what options are available to you.
Do You Need a Prescription for CPAP Supplies?
Most CPAP supplies do not need a prescription. Only CPAP machines, humidifiers, and complete masks require prescriptions. The individual parts of the mask can be replaced without a prescription.
Does Health Insurance Cover CPAP Supplies?
Most insurance plans, including Medicaid and Medicare, cover at least some of the costs of many CPAP supplies, including masks, hoses, headgear, and filters. However, coverage and purchase requirements can vary, and Medicaid coverage can differ depending on your state of residence.
Some insurers may require that you buy from approved durable medical equipment providers. Others may allow you to buy from any source and submit a reimbursement claim. Check with your provider for specific coverage details.
Can You Use an FSA or HSA Account for CPAP Supplies?
CPAP supplies are considered medical expenses and are thus eligible purchases with a flexible spending account (FSA) or a health savings account (HSA).
Where Can You Buy CPAP Supplies?
You can buy CPAP supplies online and at brick-and-mortar medical supply stores. Online shopping provides greater selection and the ability to compare prices across sites. Many websites feature email and chat options to help you find the right supplies. A physical store may be preferable if you prefer to talk with someone in person or would like to see the accessories before purchasing.

Regular cleaning helps keep your CPAP equipment safe, hygienic, and working properly. Without proper care, moisture and debris can lead to bacteria buildup, odors, and reduced performance.
Daily Cleaning
- Empty and rinse the humidifier water chamber with warm water.
- Wash or wipe down the mask cushion to remove oils and residue.
- Let all parts air dry completely before use.
Weekly Deep Cleaning
- Wash the mask, tubing, and water chamber with warm water and a mild, fragrance-free soap.
- Gently scrub with a soft cloth or brush to remove buildup.
- Rinse thoroughly and allow all components to air dry on a clean surface.
Additional Tips
- Replace water daily and use distilled water in the humidifier to prevent mineral buildup.
- Clean or replace filters regularly based on manufacturer guidelines.
- Avoid harsh chemicals or unapproved cleaning methods, as they can damage equipment.

Frequently Asked Questions
Other than your mask, everything you need to get started using your CPAP machine will be in the box. This includes a hose, filter, and a water chamber if your machine has a humidifier. However, you'll need to get replacement supplies soon after receiving your machine, as some of the parts should be switched out within a few weeks.
If your supplies arrive in original sealed packaging from a reputable source, you may not need to wash them before use. However, you should always refer to the instructions for product specifics. If it makes you more comfortable, you can clean the items before the first use. As long as you are following proper cleaning procedures, this shouldn't cause any issues.
While CPAP supplies aren't directly included in the Internal Revenue Service’s publication of eligible medical expenses, the IRS does list oxygen equipment used for breathing problems as a deductible expense. Speak with a tax professional to confirm if your CPAP expenses meet the criteria for tax deduction.
The best option for donating CPAP supplies is through an organization that handles durable medical equipment. In many places, there are local nonprofit organizations that will work with you to assess the items you have and determine what can be donated. If there are none in your area, charitable groups like the American Sleep Apnea Association and The Reggie White Sleep Disorders Research and Education Foundation have mail-in programs for gently used CPAP machines and factory-sealed supplies.
